Furthermore, only three different types of polygons comprise the faces of the five Platonic solids – the triangle, the square and the pentagon.

Also, three of the five Platonic solids have vertices where three faces meet – the tetrahedron, the hexahedron (cube), and the dodecahedron. Three of the five Platonic solids have triangular faces – the tetrahedron, the octahedron, and the icosahedron. For instance, 1368 and its reverse 8631 are both divisible by three (and so are 1386, 3168, 3186, 3618, etc.).

Because of this, the reverse of any number that is divisible by three (or indeed, any permutation of its digits) is also divisible by three. A natural number is divisible by three if the sum of its digits in base10 is divisible by 3.įor example, the number 21 is divisible by three (3 times 7) and the sum of its digits is 2 + 1 = 3. If n is greater than 2, both n − 1 and n + 1 are greater than 1 so their product is not prime. This is true for 3 as well (with n = 2), but in this case the smaller factor is 1. Any other number which is n 2 − 1 for some integer n is not prime, since it is ( n − 1)( n + 1). Three is the only prime which is one less than a perfect square. “To succeed in life, you need three things: a wishbone, a backbone and a funny bone.” Reba McEntire Interesting Knowledge about the Number 3 In this 11-part series, we explain the deeper meanings or most significant characteristics of a number, and in this article our focus is on the Numerology Meanings of Number 3 Energy (the previous two dealt with the Numerology Meanings of Number 1 Energy and the Numerology Meanings of Number 2 Energy).
